Thermoduct manual volume controllers
Thermoduct manual volume controllers
With a thermoduct manual control damper, you can (manually) control the flow of air through a spiro tube yourself. The various products on this page all feature a manually adjustable damper blade, which you can also lock in place. Another advantage is the thermoduct insulated exterior. This ensures that heat transfer is reduced. The insulation material is applied to the outside of the thermoduct and helps to maintain the temperature of the air inside the thermoduct during its transport. This helps to save energy and improve the efficiency of the ventilation system. You can easily fit these thermoduct control valves, by simply inserting them into the ventilation duct. Thanks to the rubber seal, airtightness class D (ATC 2) can be achieved and no further installation material is required. You can choose from control valves in various diameters, with a range between 125 mm and 450 mm.
